Refractaloy 26 is Fe – NI – Co – Cr precipitation hardening type deformation of high temperature alloy, long-term use of C – 570 ℃ temperature range of 540 ℃, the highest temperature can reach 677 C, add element of a Cr, mo alloy solid solution strengthening, high to low titanium, aluminum form y aging strengthening phase, while drilling elements made of titanium, aluminum solubility in the solid solution is reduced, prompted y phase precipitation amount increase, so as to improve the thermal stability of y, reduce y ‘phase of the stacking fault energy.

The composite properties of the alloy are superior, with excellent tensile resistance, force relaxation and creep resistance, no notch sensitivity.
